Write an equivalent expression for each question

Mandarinka [93]

Answer:

A. 16 - 4 x = 4(4 - x)

B. 4 x + 8 = 4( x + 2)

C. -8 b - 24 = -8(b + 3)

D. 54 + 9 x = 9 (x + 6)

Step-by-step explanation:

Here, the given expressions are:

A. 16 - 4 x

Now, 16 and 4 have 4 as their COMMON FACTOR.

⇒Taking out 4 as the factor, we get: 16 - 4 x = 4 ( 4 - x)

Hence, the equivalent expression of 16 - 4 x = 4 ( 4 - x)

B. 4x + 8

Now, 4 and 8 have 4 as their COMMON FACTOR.

⇒Taking out 4 as the factor, we get: 4 x + 8 = 4 ( x + 2)

Hence, the equivalent expression of 4 x + 8 = 4 ( x + 2)

C. -8b - 24

Now, -8 and -24 have (-8) as their COMMON FACTOR.

⇒Taking out (-8) as the factor, we get: -8b - 24 = (-8) ( b+ 3)

Hence, the equivalent expression of -8b - 24 = (-8) ( b+ 3)

D. 54 + 9x

Now, 54 and 9 have (9) as their COMMON FACTOR.

⇒Taking out (9) as the factor, we get: 54 + 9 x = 9( 6 + x)

Hence, the equivalent expression of 54 + 9 x = 9( 6 + x)

eimsori [14]

For this question you need to use the formula: y=p(1+r)^t. P is the principle, or the starting amount, $10,000, r is the rate of growth or decay, and t is the number of years. y=10,000(1.05)^x

Diego buys 4.25 pounds of mushrooms. Each pound costs $2.99. Which expression gives the best estimate of the cost of the mushroo

Vadim26 [7]

Answer:

(4)($3)

Step-by-step explanation:

Given parameters:

Quantity of mushroom bought = 4.25pounds

Cost of each mushroom = $2.99

Unknown:

Best estimate for the cost of the mushroom = ?

Solution:

The cost of the mushroom is:

Total cost = quantity of mushroom bought x cost of each mushroom

Total cost = 4.25 x 2.99

You can round 4.25 to 4 and 2.99 to 3

Or 4 x 3 = $12

How to slove y=-3x+4

garik1379 [7]

Equation By Substitution/Elimination Method:

y = -3x + 4; y = 4x - 10

Let's solve your system by substitution.

y = −3x + 4; y = 4x − 10

Step: Solve y = −3x + 4 for y:

y = −3x + 4

Step: Substitute −3x + 4 for y in y = 4x − 10:

y = 4x − 10

−3x + 4 = 4x − 10

−3x + 4 + −4x =4x − 10 + −4x (Add -4x to both sides):

−7x + 4 = −10

−7x + 4 + −4 = − 10 + −4 (Add -4 to both sides):

-7x = -14

-7x/ -7 = -14/ -7 ( Divide both sides by -7):

x = 2

Step 2: Substitute 2 for x in y = −3x + 4:

y = −3x + 4

y = (−3)(2) + 4

y = −2 (Simplify both sides of the equation)

Answer:

x = 2 and y = −2
